A reliable method for monitoring stress and burnout among medical students is critically needed. To address this gap, our team aims to utilize the cost-effective WHOOP strap 4.0 wearable device to continuously capture stress-relevant physiologic data (i.e., sleep hours, heart rate variability, respiration rate, resting heart rate) among up to 50 third-year medical students at 24 Sidney Kimmel Medical College at Thomas Jefferson University for 6 months.
Aim 1: To determine whether physiologic metrics of sleep and heart rate variability correlate with subjective assessments of medical student wellness in a 6-month period.
Hypothesis: Less total sleep hours will correlate with higher scores for Perceived Stress Scale-4, Medical Student Well-Being Index, and Patient Health Questionnaire-9, but lower heart rate variability will correlate with higher scores on Perceived Stress Scale-4, Medical Student Well Being Index, and Patient Health Questionnaire-9.
Aim 2: To determine whether physiologic metrics of sleep and heart rate variability correlate with performance on shelf examinations for clinical rotations in a 6-month period.
Hypothesis: Less total sleep hours and lower heart rate variability will correlate with poorer performance on shelf examinations.
